Hello! Sorry I haven't introduced myself, I just purchased a Silverado a couple days ago from a used car dealership (did get it checked out by mechanic), and I'm starting to work on some known (hopefully minor) problems. We bought the truck to pull a horse trailer. The biggest and most urgent issue is the turn signals, which I hope is actually relatively easy to fix. -Neither hazards or turn signals work, neither light up the bulbs at all, not coming on at all - -Checked all fuses, bulbs, replaced flasher. No change -All other lights work, brake lights work, all other controls from the turn signal switch work. Should I go ahead and replace the turn signal switch? Since the part itself it a bit pricey, I'm trying to make sure that's the right thing to do before I start pulling things apart. We're thinking it's not an issue with wiring/grounding because all the other lights in the truck (both front and rear) are fully functional. Is that an OK assumption to make? Thanks so much for your help/comments! I hope I put this in the right thread, I'll have to read through the site more as I get to know my new truck!
